WebNMS SNMP API - Free Edition

WebNMS SNMP API offers a comprehensive development toolkit for SNMP-based network management applications. WebNMS's SNMP stack comprises a set of powerful Java SNMP library to build real-time applications for monitoring and tracking network elements that are reliable, scalable, and OS independent.The Java SNMP library provides off-the-shelf components for trap and table handling along with basic SNMP operations, such as SNMP GET, SNMP GETNEXT, SNMP GETBULK, and SNMP SET. These components enable simple and rapid development and deployment of SNMPv1, SNMPv2c, and SNMPv3 management applications.The SNMP management application (manager) built using the Java-based SNMP API can receive SNMP traps, which can be processed based on predefined criteria for effective SNMP management.
WebNMS SNMP API completely supports SNMPv3, as it is compliant with RFC 3411, 3412, 3413, 3414, and 3415. WebNMS SNMP API provides an elegant way of implementing the security and access controls. Users can also define and implement their own security and access control model. Default implementation of USM and VACM based security models are offered using these frameworks. Also, SNMP API has the provision to store the v3 configuration data in a database. This is particularly useful when managing large number of SNMPv3 devices via WebNMS SNMP API. It also supports co-existence, notification filtering, and proxy forwarding; thus confirming to the RFC 2573 and 2576.
SNMP API can be used with two-tier as well as three-tier management applications. In the two-tier architecture, the management applications directly communicate with the agents. In the three-tier architecture, the management applications communicate with the agents through a manager-server. For building highly scalable management applications, three-tier architecture is the best option.
